This is a first-time setup and it includes a CustomFit aluminum frame. After your setup, you’ll only need to purchase the CustomFit filter refills since the frame has been installed.
A custom measured aluminum frame for your air conditioner’s filter is the only way to ensure your filter is at 100% efficiency. Cardboard an plastic frames bend and warp, aluminum stays rigid and keeps a tight seal around your filters. This means your AC will only pull air in that is 100% filtered and keep your AC healthier for longer!
